Abstract


The author studies the effects of the variability of physical properties on the capacitance of a silicon solar cell in the presence of excitons. Some physical properties of solar cells that are within the continuity equations are strongly dependent on temperature. The problem amounts to solving the partial differential equations coupled heat, electron transport and exciton. To show the influences of parameters on the capacitance to generalize the study, the author adimensionalized the equations by introducing characteristic sizes. The equations obtained are coupled together and also coupled with the boundary conditions, a digital resolution approach is then imposed. The algebraic systems obtained after spatial discretization (for a scheme of control volume) are determined using the dual scan method. The spatial variation of the capacitance as a function of the coupling coefficient, the number fourier, of the heating factor are given and analyzed.
